AZ® 10XT (220CPS) Thick Resists for High Resolution   General Information Compared to the AZ® 4500 series, the AZ® 10XT resists have a lower optical absorption. This simplifies the exposure of (also very) thick resist films. Therefore, in combination with the missing g-line sensitivity, the AZ® 10XT series needs a higher exposure time under broadband condition, and reveals a lower development rate as compared to AZ® 4500 films processed under the same conditions. On the other hand, the AZ® 10XT shows a very high aspect ratio and resolution. For lower resist film thicknesses we recommend a dilution with PGMEA = AZ® EBR Solvent. The following resist film thicknesses refer to 4000 rpm under standard conditions: 4.0 µm: 100g AZ® 10XT + 13g PGMEA 3.0 µm: 100g AZ® 10XT + 23g PGMEA 2.0 µm: 100g AZ® 10XT + 42g PGMEA 1.5 µm: 100g AZ® 10XT + 55g PGMEA 1.0 µm: 100g AZ® 10XT + 88g PGMEA The AZ® 10XT is a PFOS-free alternative to the AZ® 9260, which was discontinued in 2019. Viscosity and process parameters are identical to the former AZ® 9260.   3.0 µm lines in 12 µm thick AZ® 10XT Ultratech 1500 Exposure, AZ® 400K Developer 1:4 (260s spray)   Product Properties Good resist adhesion to all common substrate materials Compatible with all common developers (KOH- or TMAH-based) Compatible with all common strippers (e.g. with AZ® 100 Remover, organic solvents or aqueous alkaline) h- and i-line sensitive (approx. 320 - 410 nm) Resist film thickness range approx. 5 - 30 µm Developers The recommended developers for the AZ® 10XT photoresist are AZ® 400K 1:4 or AZ® 726 MIF. In case of very thick resist films, a rather strong developer concentration such as AZ® 400K 1:3.5 - 1:3.0 might be reasonable for required short development times. Removers For non cross-linked resist films the AZ® 100 Remover, DMSO or other common organic solvents can be used as stripper. If the resist film is cross-linked (e.g. by high temperature steps > 140°C, during plasma processes such as dry etching or during ion implantation), we recommend the NMP-free TechniStrip P1316 as remover. AZ® 920 Remover can be a good choice as well, in case of harsh treated, hard to remove resist residuals. Thinning/ Edge Bead Removal We recommend for thinning the AZ® EBR Solvent.

AZ® 40XT Chemically Amplified Thick Photoresist   General Information AZ® 40XT for 15 - 100 µm Resist Film Thickness (i-line) The chemically amplified AZ® 40 XT is an ultra thick resist whose high viscosity allows very large resist film thicknesses via a single coating. It does not require rehydration, requires low light doses, releases no nitrogen during exposure and develops very rapidly, thus permitting significantly shorter process times compared to standard thick resist films. However, the AZ® 40XT necessarily requires a Post Exposure Bake to be developed. Remark: The maximum soft bake temperature must not be applied abruptly, in order to prevent the formation of bubbles in the resist film. We recommend either the usage of a proximity hotplate, or a temperature ramp on a contact hotplate. The correct temperature ramps are crucial for bubble free resist processing with this resist.   Lines and spaces varying from 100 to 10 µm with a 40 µm thick AZ® 40XT at 400 mJ/cm2 exposure dose Product Properties 15 - 100 µm resist film thickness via single-coating Aqueous alkaline developers (e.g. AZ® 326/726/2026 MIF) No rehydration required, no N2-formation during exposure Very good adhesion, very steep resist sidewalls Can be stripped wet- and dry-chemically Optimized for electroplating, wet- and dry etching i-line sensitive (approx. 330 – 390 nm) Developers We recommend common TMAH-based developers such as the AZ® 326 MIF, AZ® 726 MIF or AZ® 2026 MIF developer. Removers AZ® 40XT photoresist is compatible with industry standard solvent based removers (e.g. NMP, DMSO, AZ® 920 Remover or Technistrip MLO07). Thinning/ Edge Bead Removal We recommend for thinning and edge bead removal AZ® EBR Solvent or PGMEA. AZ® EBR70/30 Solvent is possible as well for edge bead removal.

AZ® 4533 (3.3 µm resist film thickness at 4000 rpm) and AZ® 4562 (6.2 µm) have a lower photoinitiator con¬centration compared to thin resists. This makes it possible to process thick resist films over 10 µm without N2 bubble formation, but at the expense of a significantly lower development rate. Product Properties Optimized resist adhesion to all common substrate materials Broad process parameter window for stable and reproducible litho-processes Compatible with all common developers (KOH- or TMAH-based) Compatible with all common strippers (e.g. with AZ® 100 Remover, organic solvents, or aqueous alkaline) g-, h- and i-line sensitive (approx. 320 - 440 nm) Resist film thickness range approx. 2.5 - 5 µm Developers If metal ion containing developers can be used the KOH-based AZ® 400K in a 1:4 dilution or the finish diluted version AZ® 400K 1:4 (for higher resist film thicknesses 1:3.5 - 1:3 diluted possible) is a suited developer. If metal ion free developers have to be used, we recommend the TMAH-based AZ® 2026 MIF developer (undiluted). Removers For non cross-linked resist films the AZ® 100 Remover, DMSO or other common organic solvents can be used as stripper. If the resist film is cross-linked (e.g. by high temperature steps > 140°C, during plasma processes such as dry etching, or during ion implantation), we recommend the NMP-free TechniStrip P1316 as remover. AZ® 920 Remover can be a good choice as well, in case of harsh treated, hard to remove resist residuals.

AZ® 4562 Thick Resists with Optimized Adhesion   General Information The AZ® 4500 series (AZ® 4533 and AZ® 4562) are positive thick resists with optimized adhesion for common wet etching and plating processes. The AZ® 4500 series follows the AZ® 1500 series in the attainable and processable resist film thickness range. AZ® 4533 (3.3 µm resist film thickness at 4000 rpm) and AZ® 4562 (6.2 µm) have a lower photoinitiator con¬centration compared to thin resists. This makes it possible to process thick resist films over 10 µm without N2 bubble formation, but at the expense of a significantly lower development rate. A resist film thicknes up to 30 µm can be achieved by single-coating with adjusted spin profiles (short spin times at medium spin speed). Higher layer thicknesses can be achieved by multiple coating. Higher film thickness attainable with multiple coating. Please note: Resist Film Thicknesses > 30 µm Generally, the AZ® 4562 can be coated and processed up to 30 µm and beyond. However, softbake, rehydration, exposure and development become very time-consuming in this thickness range. Additionally, even the rather transparent AZ® 4562 photoresist may form N2-bubbles during exposure when applied too thick. Therefore, for resist film thicknesses > 20 µm, we strongly recommend the chemically amplified AZ® 40XT. Product Properties Optimized resist adhesion to all common substrate materials Broad process parameter window for stable and reproducible litho-processes Compatible with all common developers (KOH- or TMAH-based) Compatible with all common strippers (e.g. with AZ® 100 Remover, organic solvents, or aqueous alkaline) g-, h- and i-line sensitive (approx. 320 - 440 nm) Resist film thickness range approx. 5 - 30 µm Developers If metal ion containing developers can be used the KOH-based AZ® 400K in a 1:4 dilution or the finish diluted version AZ® 400K 1:4 (for higher resist film thicknesses 1:3.5 - 1:3 diluted possible) is a suited developer. If metal ion free developers have to be used, we recommend the TMAH-based AZ® 2026 MIF developer (undiluted). Removers For non cross-linked resist films the AZ® 100 Remover, DMSO or other common organic solvents can be used as stripper. If the resist film is cross-linked (e.g. by high temperature steps > 140°C, during plasma processes such as dry etching, or during ion implantation), we recommend the NMP-free TechniStrip P1316 as remover. AZ® 920 Remover can be a good choice as well, in case of harsh treated, hard to remove resist residuals. Thinning/ Edge Bead Removal We recommend for thinning and edge bead removal AZ® EBR Solvent.

AZ® 5209E Image Reversal Resist for High Resolution   General Information This special photoresist is the thinner version of the AZ® 5200E series intended for lift-off techniques which call for a negative side wall profile. The reversal bake moderately cross-links the exposed resist making the developed structures thermally stable up to approx. 130°C. Due to the comparably low resist film thickness of ~ 0.9 µm, the process parameter window for an undercut is rather small thus requiring some optimizations in the exposure dose and the reversal bake parameters. Therefore, if the resolution required is not in the sub-µm range, a thicker resist such as the AZ® LNR-003 (next section), or the AZ® nLOF 2000 negative resists might be a good alternative. Product Properties Very high resolution as a positive resist as well as a negative resist Possible negative sidewall profile in image reversal mode Compatible with all common developers (NaOH-, KOH- or TMAH-based) Compatible with all common strippers (e. g. with AZ® 100 Remover, organic solvents, or aqueous alkaline) h- and i-line sensitive (approx. 320 - 405 nm) Resist film thickness range approx. 0.7 - 1.2 µm High thermal stability especially in image reversal mode Developers If metal ion containing developers can be used, the NaOH-based AZ® 351B in a 1:4 dilution (for a required resolution < 1 µm 1:5 dilution recommended) is a suited developer. The KOH-based AZ® 400K (also 1:4 - 1:5 diluted) is also possible. If metal ion free developers have to be used, we recommend the TMAH-based AZ® 726 MIF or AZ® 326 MIF developer, normally undiluted, or - for maximum resolution - moderately 3:1 - 2:1 (3 parts Developer :1 part of DI-Water) diluted with water. Removers For non cross-linked resist films the AZ® 100 Remover, DMSO or other common organic solvents cab be used as stripper. If the resist film is crosslinked (e. g. by high temperature steps > 140°C, during plasma processes such as dry etching, or during ion implantation), we recommend the NMP-free TechniStrip P1316 as remover. AZ® 920 Remover can be a good choice as well, in case of harsh treated, hard to remove resist residuals.
